Established a deductible payment system where owners must pay $2,000 for the first claim, $10,000 for the second claim, and $20,000 for subsequent claims at a facility before receiving state funding.

Created new eligibility requirements for funding, including proof of financial responsibility (such as a self-insurance test or restricted deposit account) and confirmation that the facility is in compliance with registration and fee requirements.

Mandated that owners submit work invoices to the administrator within 60 days of performing work to receive reimbursement, with expenses required to be reasonable and documented.

Clarified that multiple claims arising from the same release or a series of related releases will be treated as a single claim subject to one deductible amount.
